Jet Streak Circulations

Jet Streak Circulations
  • Define "jetstreak"
  • Note the divergence associated with upper-level waves
  • Describe the relationship of divergence with vertical windshear
  • Describe the relationship of the ageostrophic wind components with upper-level and low-level jets
  • Compare the direct thermal circulation in the entrance region with the indirect thermal circulation in the exit region of an upper-level jet
  • Identify how the curvature of an upper-level jet affects divergence and convergence
  • Describe the impact thermal advection has on vertical motion and entrance and exit circulations
  • Gain an understanding of the characteristics of unbalanced jets and coupled jets
